Two sinusoidal sound waves arrive at a receiver 90.0° out of phase. Waves #1 has a pressure amplitude Po at the receiver and wave #2 has a pressure amplitude 0.600p, at the receiver. a) Make a free-hand sketch (you don't need to use a ruler) with approximately correct relative lengths for the phasors to show the individual phasors and their sum. Label the phasors as p1, p2, and pnet- b) Find the pressure amplitude for the net wave in terms of Po.
